Did some deep searching. http://ece.gmu.edu/~pceperle/projs513/Nishanian/RadioP.htm Ok too many equations, no pictures.
http://www.s3.kth.se/radio/COURSES/RKBASIC_2E1511_2001/lecture_3.pdf I like this one, it has pictures and is easy to understand. Has pratical microwave pieces in it as well. http://www.j-walk.com/other/wifispray/ No need for calculations, just use wifispray :) ----- Original Message ----- From: "Loren Zemenick" <[EMAIL PROTECTED]> To: "Brian Lloyd" <[EMAIL PROTECTED]>; <[EMAIL PROTECTED]> Sent: Tuesday, August 26, 2003 8:59 PM Subject: RE: [BAWUG] Microwave propagation speed versus air temperature > Tropospheric ducting may be an overstatement.
